SOLE-PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 651,406, dated June 12, 1906.

Application filed June 21, 1899. Serial No. 721,317. (No model.)

To all whom it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Sole-Pressin Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates generally to sole-pressing machines, such as sole-leveling and sole-laying machines, and more particularly to sole-pressing machines commonly known as direct-pressure machines wherein the sole of the shoe mounted on the jack or form is compressed and leveled or laid, as the case may be, by pressure applied in a direct line over the entire surface of the sole.

The object of the present invention is to provide in a machine of the direct-pressure type wherein the pressure is intermittently applied to the shoe-sole means whereby after each compression of the sole the form and jack will be given relative incremental approximating movements or caused to approach each other to substantially the extent of the reduction in thickness of the sole caused by the preceding compression.

To the above end the present invention consists of the devices and combinations of devices, which will be hereinafter described and claimed. r

The present invention is illustrated in the accompanying drawings, in which- Figure 1 shows in side elevation a machine embodying the invention. Fig. 2 shows in plan'portions of the mechanism for actuating the jacks and forms. Fig. 3 shows in section and side elevation portions of the mechanism shown in Fig. 2, taken on the line 00 w and looking in the direction of the arrow, Fig. 2; and Fig. 4 is a similar view with the parts in a different position.

In the accompanying drawings I have illustrated the present invention as being embodied'in the machine disclosed in Letters 7 and for the purpose of describing the present invention, and it is to be distinctly under stood that the present invention is in nowise As in the patented machine, the jacks and 1 forms are preferably relatively actuated to seat the form on the sole of the shoe, which may be on the jack beneath the form, and thereafter the jacks and forms are relatively actuated to subject the shoe-sole to pressure between the form and the bottom of the last. As in the patented machine, the forms are carried by a vertically-movable cross-head,which is permitted to fall by gravity to seat one of the forms on the shoe-sole, and said cross-head is raised by means of a bell-crank lever 5, ful crumed at 6, one arm of which carries a seg ment 7, engaging a rack carried by a block 8, secured to a rod depending from the crosshead carrying the forms, the other arm of the bell-crank lever carrying a cam-roll 9, which is arranged to be engaged by a peripheral cam 10. The locking of the forms with one of them seated on the shoe-sole to prevent their upward movement is secured by means of cams 11, one only of which is shown, carried by a shaft 12. The shaft 12 is actuated by means of a spring (not shown) to force the locking-cams in contact with the cross-head carrying the forms to lock the same against upward movement, and the shaft 12 is rotated in an opposite direction to remove the locking-cams and permit the cross-head and forms to be raised by means of a lever 13, fulcrumed at 14 and carrying at its upper end a segmental rack 15, engaging a pinion (not shown) on the shaft 12, the lower end of the lever. carrying a cam-roll, which engages the peripheral cam 16. The cross-head 1 is raised and lowered to secure pressure by means of toggles 17 and 18, which are actuated by a link 19 engaginga cam-groove (not shown) in a cam 20.

The machine as so far described and except as hereinafter pointed out is in all respects constructed and operated as the machine of the patent hereinbefore mentioned and a further description thereof in the present specification is deemed unnecessary. As in said patented machine, the cam 20, which actu ates the toggle-levers 17 and 18, is fixedly mounted on a cam-shaft 21, which at one end car ries a gear 22, which is engaged and driven by a pinion 23, carried by the driving-shaft 24, which at one end carriesa belt-pulley 25, splined to said shaft and carrying one member 26 of a clutch arranged to be engaged with and disconnected from a complementary clutch member 27, fixedly mounted on the shaft 24. The clutch is controlled by a sliding and turning clutch-rod 28, which is actuated by means of a spring 29 to couple the clutch members 26 and 27 and which at its free end carries an arm 30, which is normally held in position to be engaged by a dog 31, carried on the inner face of the gear 22, the arrangement being such that the spring 29 whenever the rod 28 shall be rocked to disengage the arm 30 from the dog 31 will slide the rod along and force the clutch members 26 and 27 together, thereby permitting the shaft 24 to be rotated and imparting through the pinion 23 and gear 22 a rotary movement to the cam-shaft 21. The rod 28 is controlled by means of a foot-treadle 32,which is f ulcrumed to the frame at 33 and is connected to a rod 34, carrying a cross-pin 341, which engages a notch in the upper surface of a lever 35,which lever is pivotally connected by means of a link 36 to an arm 37, fixedly secured to the shaft 28, whereby a depression of the foottreadle 32 will impart a downward movement to the lever 35 and by means of the link 36 and arm 37 rock the shaft 28 to remove the arm 30 from contact with the dog 31 and permit the spring 29 to couple the clutch members, and when the operator releases the treadle 32 the lever 35 will, under certain conditions to be hereinafter described, be raised by means of a spring 38, connected to said lever and to the fixed part of the frame, thus rocking the rod 28 and returning the arm 30 to the position to be engaged by the dog 31 to move the rod 28 laterally to disconnect the clutch members and stop the operation of the machine.

As hereinbefore set forth, in the present machine the pressure-forms andjacks are to be relatively actuated by means under the control of the operator to impart intermittent compressions to the shoe-sole, which intermittent compressions will be continued as long as it is deemed necessary by the operator.

Any suitable mechanism may be adopted for producing the intermittent compressive action referred to; but in the illustrated embodiment of the present invention I have secured the desired operation of the machine in the following manner: The cam 20, which actuates the toggle-levers 17 and 18 to impart movement to the table 1 and the jacks and shoes thereon toward and from the pressureforms, is fixedly secured to the shaft 21, and thus will turn with said shaft to actuate the toggle-levers to move the table and jacks, as described, so long as the rod 28 remains turned with the arm 30 out of the path of movement of the dog 31, with the spring 29 holding the clutch members 26 and 27 coupled together. The cams 10 and 16, which control the seating and locking of the forms, are loosely mounted on the shaft 21 and are arranged to be connected thereto at times by a suitable clutch,whereby said cams will be turned,with the shaft 21. and the cam 20, at times to either actuate the levers 13 and 5 to remove the locking devices 11 from contact with the crosshead carrying the pressure-forms and to raise the said forms, at which time the cams will be in substantially the position illustrated in Fig. 4 or to turn said cams to substantially the position shown in Fig. 3 to permit the pressure-forms to fall to seat one of them on the sole of a shoe which may be on the jack then in position under one of said forms and to force the locking devices into position to engage the cross-head carrying said forms to prevent its being moved upward as the pressure is applied by the upward movement of the table 1 and the jack.

Means are provided for automatically disconnecting the clutch which looks the cams 10 and 16 to the shaft 21 whenever said cams shall have been moved to either the position shown in Fig. 4, with the locking devices and pressure-forms elevated, and also when said cams shall have been moved to the position shown in Fig. 3 to permit the pressure-forms to be seated 011 the shoe-sole and the locking devices to be thrown into action, and I have provided connected mechanism whereby when the cams shall have been moved to the position shown in Fig. 3 by the rotation of the shaft 21, with the forms seated and the looking devices thrown into action, the lever 35 will be held depressed, with the rod 28 turned to such position as to remove the arm 30 from the path of movement of the dog 31, thus permitting a continuous operation of the shafts 24 and 21 and the pressure-securing cam 20, while the cams 10 and 16 remain at rest.

The mechanism for securing the above-desired result in the machine of the drawings is constructed and arranged as follows: The cams 10 and 16 are formed on a sleeve 39, which at one end carries one member of a clutch 40, which is shown as comprising a disk having a recess 41 in one face thereof, in which is secured a pin 42, projecting a short distance beyond the base of the recess 41. The complementary clutch member shown as a disk43, fitting into the recess 41 of the clutch member 40 and provided with a pin 44, arranged to engage the pin 42 of the clutch member 40, the clutch member 43 be ing fixedly secured to' the shaft 21 in any suitable or convenient manner. The sleeve 39,

carrying the cams '10 and 16, is forced, together with the clutch member 40, toward the clutch member 43 by means of a spring 45, surrounding the shaft 21 and bearing at one end against the sleeve 39 and at its opposite end against the inner face of the cam 20. WVhenever the sleeve 39 shall have been moved to the position shown in Fig. 2 of the drawings by means of the spring 45, the clutch members 40'and 43 will be coupled together by the pins 42 and 44 engaging with each other, thus imparting a rotary movement to the sleeve 39 and the cams 10 and 16 with the shaft 31 and the cam 20. In order to move the sleeve 39 laterally along the shaft 21 against the tension of the spring 45, and thus disconnect the clutch members 40 and 43, I have provided a lever 46, which is substantially like the lever 35, the said levers being placed adjacent to each other, as shown in Fig. 2, and fulcrumed at their rear ends upon the shaft 47. The lever 46, like lever 35, is normally held in an elevated position by means of a spiral spring 48, which at one end is connected to said lever and at its opposite end to some fixed portion of the frame, and, like lever 35, the lever 46 is engaged by the cross-pin 341 of rod 34.

The lever 46 is provided upon one side with a rounded projection or dog 49, which when the lever 46 is held in an elevated position is in the path of movement of a beveled dog 50, carried by the inner face of the cam 10, which when it engages the dog 49 causes the sleeve 39 to be moved laterally to the left as the mechanism is viewed in Fig. 2, and thus disconnects the clutch members 40 and 43, leaving the shaft 21 free to rotate, while the cams 10 and 16 remain at rest. Upon the sleeve 39 is formed a projection 51, which when the sleeve 39 shall have been moved to the left, as described, will be brought over the lever 35 in position to engage a rounded projection or boss 52 on said lever to depress the lever 35 and, by means of the link 36 and arm 37, maintain the clutch-rod 28 in such position that the arm 30 will be out of the path of movement of the dog 31, and this depression of the lever 35 or the-engagement'of the boss or lug 51 therewith occurs simultaneously, or substantially so, with the movement of the sleeve 39 along the shaft 21 by means of the beveled dog 50 engaging the projection 49 on the lever 46 to disconnect the clutch members 40 and 43, as hereinbefore described,

. and thereafter the shaft 21 will continue to 40 and 43, whereupon the cams 10 and 16 will be moved to the position shown in Fig. 4, actu-' ating the levers 5 and 13 to remove the locking devices 11 from above the cross-head carrying the pressure-forms to raise such forms. Thereafter, the projection 51 being removed from contact with the lever 35, the springs 38 and 48 will act to raise the levers, as shown in Fig. 4 of the drawings, the-raising of the lever 35 acting, through the link 36 and arm 37, to place the arm 30 of the clutch-rod 28 in the path of movement of the beveled dog 31, which when it engages such arm will move the clutch-rod 28 to the right against the tension of the spring 29, thus disconnecting the clutch members 26 and 27 and stopping the machine.

It is to be observed that the pressure-forms move toward the shoe-sole and are seated thereon by gravity, and, as in the patented machine referred to, the locking-cams are forced into their locking position by a spring, (not shown,) which surrounds the shaft 12, upon which said locking-cams are mounted, and that therefore the tendency of the pressure forms both under the influence of gravity and also by reason of the action of the lookingcams on the cross-head which carries said forms is to move downward toward the jack or the sole of the shoe mounted thereon, so that as the shoe-sole is compressed and shaped to the bottom of the last and to a certain extent compacted and reduced in thickness by the successive compressive reciprocations of the jack toward and away from the form the tendency of the form will be to follow up, as it were, or by successive increments approximate more closely to the jacks and automatically position themselves to adjust the pressure to the variations in thickness of the sole produced by thesuccessive and repeated compressions thereof.

Inasmuch as the sleeve 39 and the cams 10 and 16 when in the position shown in Fig. 3 of the drawings will be entirely disconnected from the shaft 21 and while in this position the bulk of their weight is in such a position as to cause a tendency of such cams to fall, it may be desirable to employa brake to maintain the cams in that position, and for this purpose I have secured a brake'arm 53, fixedly secured to the shaft 47, carrying a shoe 54, against which the side of the cam 10 is adapted to be forced as it is moved laterally by the engagement of the dog 50 with the projection 49. The portions of the machine not herein sufficiently illustrated and described may be and preferably are the same as corresponding parts of the machine of the patent and are constructed, organized, and operate in substantially the same manner as defined in said patent.

It will be noted that while'I have in the foregoing specification and' accompanying drawings described and illustrated the present invention as embodied in a duplex machine comprising two jacks and their cooperating pressing-forms i desire it to be dis, tinctly understood that the invention is not limited to such an embodiment thereof, as it may be equally desirable to embody the same in a sole-pressing machine comprising but a single jackand form.

Having described the construction and mode of operation of my invention, I claim as new and desire to protect by Letters Patent of the United States- In a sole-pressing machine, the combination with a sh oe-supporting jack and a sole-pressing form, of mechanism for relatively actuating the jack and form to impart thereto an intermittent compressive movement, and mechanism for relatively actuating the jack and form to secure an incremental approximating movement,substantially as described. In testimony whereof I afiix my signature in presence of two Witnesses.
